Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

Evinrude 150 Ficht CHECK ENGINE prior to start

August 14th, 2006, 07:55 PM

Just replaced a cracked vapor separator cap on the motor (Year 2000 w/ less than 100 hours). THought that would be the end of my problems, but when I turn the power on and rotate the key for the built in self test, the "Check Engine" light remains illuminated. All fuel lines were reconnected, the squeeze bulb is pumped stiff, and there are no leaks. Depressing the schrader valve releases a good stream of fuel. Engine cranks but does not start up. Not sure if this is a real problem, or a hold over from the previous problem (cracked vapor separator cap) that justs needs a reset of the Check Engine system prior to it allowing me to start.

Comment

Purchased a shop manual and went through the service code retrieval process. Had one level 1 code (37) for water detected in the fuel, which makes sense, given the breach in the fuel system via the vapor separator cap.

Where's the easiest place to disconnect fuel hoses to flush the system, and can anyone recommend a straightforward process? The Clymer manual doesn't really say where to start this process, although it mentions several components to check in the system.

Will a fuel additive help "dry" out the fuel?

Comment

intruder - seems to me (i'm no expert) that the place to start is by emptying the water separator / fuel filter (#46 in the diagram below which should be for your engine). That's the only place where the "Water in Fuel Sensor" (# 14 below) 'knows' there is water. If that solves you may just want to keep an eye and you should empty out the Water Separator on the boat if you have one. Hope that helps.

Comment

THanks Tampa. I went ahead and drained the water separator / fuel filter. What had me confused was that the Clymer manual said the Water Separator was a different component than the fuel filter and I couldn't locate it based on the picture in the shop manual. There was considerable amount of water in the filter. Emptied it out, pumped several more filers full of fuel through, emptying each of them. Left it overnight and emptied once agaig (no water in filter anymore). THe Check Engine light went out, so my fuel is now relatively clean.

But, the boat still won't start, and it seems like my battery has lost its cranking ability, so I'll charge it up tonight when I get home. I also probably still need to purge whatever bad fuel might be resident in the vapor separator again since I was probably pushing bad fuel through the system for awhile.
